In the March 29 Penticton Western News, publisher Mark Walker wrote in his column “Taxpayers burned by carbon trust”:
“The climate changes over the time. We did warm up by about 0.5 C in the 1990s. Currently, global temperature, to the extent it can be measured, is dropping. Carbon dioxide has little, if anything, to do with temperature.”
I would appreciate if he could inform me about the scientific sources on which these statements are based. I would like to discuss them with our son and our daughter-in-law who both are environmental physicists who have done research in Greenland and at the South Pole.
